Neutrinos interview questions

Very bad experinece , till 2 nd round everything was good but after getting selected for 2nd round it was hell they rescheduled the interview for 5 times , and once they cancelled the interview just 5 mins before just to attend that 2nd round i took 3 days leave , please don't play with candidate time and use their job need as your advantage after 5 reschedule finally they took 2nd round interview only to tell me that what they are looking for is different, but in JD they have asked for something else If you don't want to hire , please don't hire instead of wasting someone's time who is desperately looking for a job.
